Astronomy Picture of the Day Discover the cosmos! Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. 2016 April 15 Graphene in space could hold clues to development of life on Earth An artist's concept of graphene, buckyballs and C70 superimposed on an image of the Helix planetary nebula (Image: IAC/NASA/NOAO/ESA/STScI/NRAO) Human beings may have only discovered how to create the one-atom-thick sheets of carbon atoms known as graphene in 2004 but it appears the universe could have been churning out the stuff since much earlier than that. While not conclusive proof its existence in space, NASA's Spitzer Space Telescope has identified the signature of graphene in two small galaxies outside our own. If confirmed, it would be the first-ever cosmic detection of the material and could hold clues to how carbon-based life forms such as ourselves developed.

Lindsey Caldwell « StyleLikeU I was drooling listening to Lindsey’s stories about her experience in Atlanta’s rich, underground music scene during the ’90s. She recalls what is now, sadly, an almost extinct phenomenon: sweaty nights of dancing at low-key clubs with ratty sofas, where people like Erykah Badu, Andre 3000, India Arie or Chilli might pop in and sing. Lindsey says, “Everyone wanted to know everyone… everything was a mix… it wasn’t pretentious.” For Lindsey, it was in this environment that she fell in love with drums and beats and rave and learned to be a skilled DJ, the kind with two turntables who knows how to blend songs and genres. In order to make her own imprint as a DJ, Lindsey moved to NYC with hundreds of vinyls in tow. It was while living on St.

However, analysis of Hubble measurements shows that our own Milky Way galaxy is moving toward a head-on collision with our nearest neighbor, the Andromeda galaxy (also known as M31).

SETI Astronomers Launch New Campaign to Eavesdrop on E.T. In a vast cosmic experiment equivalent to hitting "redial," astronomers in a dozen countries are aiming telescopes to listen in once again on some of the stars that were part of the world's first search for alien life 50 years ago. The coordinated signal-searching campaign began this month to mark the 50th anniversary of Project Ozma, a 1960 experiment that was christened the world's first real attempt in the search for extraterrestrial intelligence ? or SETI. Like Project Ozma, which got its name from a character in L. Frank Baum's series of books about the Land of Oz, the new search is called Project Dorothy. Project Ozma was conducted by astronomer Frank Drake of the SETI Institute in Mountain View, Calif.

Double eclipse: Moment Moon AND International Space Station cross face of Sun By Daily Mail Reporter Updated: 20:58 GMT, 5 January 2011 Britons were only offered a clouded view of yesterday's partial solar eclipse owing to our typically dreary weather. But one lucky skywatcher in south-west Asia managed to catch a doubly striking glimpse of the natural phenomenon. After some careful calculations, photographer Thierry Legault decided to travel to just outside Oman's capital city of Muscat, where he knew he could catch both the Moon and the International Space Station briefly crossing the Sun.

Advertisting Radio telescopes capture best-ever snapshot of black hole jets An international team, including NASA-funded researchers, using radio telescopes located throughout the Southern Hemisphere has produced the most detailed image of particle jets erupting from a supermassive black hole in a nearby galaxy. "These jets arise as infalling matter approaches the black hole, but we don't yet know the details of how they form and maintain themselves," said Cornelia Mueller, the study's lead author and a doctoral student at the University of Erlangen-Nuremberg in Germany. The new image shows a region less than 4.2 light-years across -- less than the distance between our sun and the nearest star. Radio-emitting features as small as 15 light-days can be seen, making this the highest-resolution view of galactic jets ever made. The study will appear in the June issue of Astronomy and Astrophysics and is available online. Mueller and her team targeted Centaurus A (Cen A), a nearby galaxy with a supermassive black hole weighing 55 million times the sun's mass.

In a dismissal that underlines his firm rejection of religious comforts, Britain's most eminent scientist said there was nothing beyond the moment when the brain flickers for the final time. Hawking, who was diagnosed with motor neurone disease at the age of 21, shares his thoughts on death, human purpose and our chance existence in an exclusive interview with the Guardian today. The incurable illness was expected to kill Hawking within a few years of its symptoms arising, an outlook that turned the young scientist to Wagner, but ultimately led him to enjoy life more, he has said, despite the cloud hanging over his future. "I have lived with the prospect of an early death for the last 49 years.

Existence: Why is the universe just right for us? - space - 29 July 2011 Read more: "Existence special: Cosmic mysteries, human questions" IT HAS been called the Goldilocks paradox. If the strong nuclear force which glues atomic nuclei together were only a few per cent stronger than it is, stars like the sun would exhaust their hydrogen fuel in less than a second. Our sun would have exploded long ago and there would be no life on Earth. If the weak nuclear force were a few per cent weaker, the heavy elements that make up most of our world wouldn't be here, and neither would you. If gravity were a little weaker than it is, it would never have been able to crush the core of the sun sufficiently to ignite the nuclear reactions that create sunlight; a little stronger and, again, the sun would have burned all of its fuel billions of years ago.
